A Hacker hijacked over 150,000 Printers publicly exposed online

Minimalist · Feb 7, 2017

Recently a group of researchers from the University Alliance Ruhr has found a cross-site printing bug in the old PostScript language. Popular printer models manufactured by Dell, Brother, Konica, Samsung, HP, and Lexmark are affected by security vulnerabilities that could be exploited by hackers to steal passwords, steal information from the print jobs, and shut down the devices.

Following the above research, a hacker with the online moniker Stackoverflowin decided to hack thousands of publicly exposed printers and to print rogue messages, including ASCII art depicting robots and warned that the printers had been hacked and they were part of a botnet.

Printer prank pushes 'PewDiePie' campaign — and points out security issue
November 30, 2018
https://www.nbcnews.com/tech/securi...ie-campaign-points-out-security-issue-n942381

[...] a hacker caused office printers to spew out the same message: “PewDiePie is in trouble.”

The message was part of a prank, carried out by a hacker identifying on the print out as “Giraffe,” that was able to find internet-connected printers and use them to reproduce a document encouraging them to subscribe to the PewDiePie YouTube account — and warning them that their printer’s security was lacking.

A search on Twitter turned up no shortage of people who had been hit by the hack — and a person claiming responsibility told NBC News they were able to compromise around 49,000 printers in total.
[...] TheHackerGiraffe said in Twitter messages with NBC News that the hack was done using publicly available code and internet resources that can find “ports,” or channels used to transfer data to devices such as printers.

Printeradvertising.com Spam Service Claims It Can Print Anywhere
December 3, 2018
https://www.bleepingcomputer.com/ne...om-spam-service-claims-it-can-print-anywhere/

According to a tweet from someone named @printerads that claims to run the site, this campaign was meant to see if anyone was interested in actually using the service. If people are interested, they would build out a service to support more printing protocols.

In response to questions from BleepingComputer, Printeradvertising has stated that this is a real service, that they on offering the service for $250 and have received over 600 emails today. Launching a service like this is no doubt illegal as they are performing unauthorized activity on someone else devices.
Printers should not be connected to the Internet
In order to prevent this type of mischief, network enabled printers should never be connected to the Internet. Allowing them to do so only allows malicious actors to send any type of print document to your network, including pornography that could land you in trouble.

PewDiePie printer hackers strike again.

Hackers have taken control of printers around the world.
It is the latest in a series of such attacks, but this time they say they have the power to destroy the machines.
The stunt was first carried out last month, when one member claimed to have forced about 50,000 printers to create posters supporting his favourite vlogger PewDiePie.
The latest incident again urges support for the YouTuber, but also calls on victims to improve their security.

'Print-related data breaches' costing businesses £313,000 per year
February 12, 2019
https://www.scmagazineuk.com/print-...ng-businesses-313000-per-year/article/1525524

The lack of security controls around old-fashioned paper and ink is leading to significant losses for organisations as they struggle to address the risks of print-related data breaches.

That’s according to a report from the analysts Quocirca – the Global Print Security report published yesterday – which makes the point that ‘low tech’ paper can be just as great a risk as an IT network breach.
Printers can be a major security weakness, as was dramatically demonstrated late last year when a mischievous hacker forced thousands of printers to spew out messages of support for the YouTuber PewDeePie.

Quocirca research director Louella Fernandes commented: "Our research consistently shows that businesses remain reliant on print, but the way it is used is changing. Print infrastructure is vulnerable to all the threats associated with IoT devices, but also to risks linked to hard copy output."
